It was that kind of night for the Los Angeles Kings, uncharacteristic on so many levels for the NHL's stingiest regular-season team.

Turnovers and mistakes.

And the Anaheim Ducks jumped all over them in a 4-3 Game 5 victory Monday night at Honda Center, finding the kind of open ice and second-chance opportunities rarely seen in this series for either team.

All four lines scored goals for the Ducks, representative of the team's depth but also its calling card when playing well, an unrelenting, four-wave attack that doesn't let the opponent come up for air.

What you saw on this night is why the Ducks finished first in the Western Conference this season.

As much as this team will always be led by Getzlaf and Corey Perry up front, what has allowed this organization to grow into a contender over the past two seasons has been the development of the supporting cast.

Nick Bonino opened the scoring Monday night. Smith-Pelly scored twice 1 minute, 23 seconds apart early in the second period. Jakob Silfverberg made it 4-1 at 8:23 of the middle frame.

Smith-Pelly was on the ice with Mathieu Perreault and Teemu Selanne on the second-unit power play for his first goal, so that means four different lines got on the scoresheet.

"You see the games we win in the playoffs so far, we've had balanced scoring," said Bonino, whose Ducks now lead the series 3-2. "We had it Game 5 last series, we had it tonight. You know what you're going to get from Getz and Perry and their line. When we can chip in with some goals and get goaltending like we got, you know you're going to have success.''

Added Ducks head coach Bruce Boudreau: "It's just something that's been going on all year, we need that depth to score. Sometimes it's not that difficult to check one line. But if you've [got] four lines with the ability to score, usually you come out ahead."

Consider what a Western Conference head coach from a rival team told ESPN.com back on May 4, the day after the Kings lost Regehr, having already been without Mitchell at that point.

"It's not so much that they've lost high, high-end defensemen, it's what they're putting in," he said.

" Matt Greene is limited. And whether it's Jeff Schultz or Andrew Campbell going in, either way, they don't trust those guys as much. Where the biggest disadvantage comes for L.A. is that Anaheim will continue to play four lines. So over time it will be become taxing to the Kings' top guys. ... If they were playing against a three-line team it wouldn't be as much an issue, but Anaheim I think will keep rolling four lines and that's going to make it more taxing on L.A.'s D-men."

Is that wear and tear showing through now? Martinez inexplicably just passed the puck right to Getzlaf outside the Kings' blue line, and the Ducks captain quickly counter-attacked on a two-on-one break to feed Smith-Pelly with a lovely pass, and the kid did the rest.
